High Performance Computing (HPC) Systems
TACC operates many of the most powerful and capable high performance computing systems in the world, which are used by thousands of scientists and engineers each year to perform research in all domains of science, including the humanities, digital media, and the arts. At nearly 10 petaflops, Stampede is now operational and available to the national open science community (as of January 7, 2013). Stampede is one of the world's most comprehensive systems for the open science community as part of the National Science Foundation's (NSF) XSEDE (formerly NSF TeraGrid) program. After five years of stellar performance and contributions to open science, Ranger will retire on February 4, 2013. At 579.4 teraflops, Ranger was the most powerful and capable HPC system in the NSF TeraGrid when it was deployed in February 2008. Additionally, Lonestar 4, which went online in February 2011, clocks in at more than 302 teraflops and offers nearly 200 million computing hours per year to researchers.
STAMPEDE
Dell PowerEdge C8220 Cluster with Intel Xeon Phi coprocessors
Stampede is one of the largest computing systems in the world for open science research. As an NSF Track2 HPC acquisition, this system provides unprecedented computational capabilities to the national research community enabling breakthrough science that has never before been possible. The scale of Stampede delivers opportunities in computational science and technology research, from highly parallel algorithms to high-throughput computing, from scalable visualization to next generation programming languages.
LONESTAR
Dell Linux Cluster
Lonestar is a powerful, multi-use cyberinfrastructure HPC and remote visualization resource. The system contains 22,656 cores within 1,888 Dell PowerEdgeM610 compute blades (nodes), 16 PowerEdge R610 compute-I/Oserver-nodes, and 2 PowerEdge M610 (3.3GHz) login nodes. Each compute node has 24GB of memory, and the login/development nodes have 16GB. The system storage includes a 1000TB parallel (SCRATCH) Lustre file system, and 276TB of local compute-node disk space (146GB/node).
RANGER
Sun Constellation Linux Cluster - Decommissioned
Ranger was one of the largest computing system in the world for open science research. As the first of the new NSF Track2 HPC acquisitions, this system provided unprecedented computational capabilities to the national research community and ushered in the petascale science era. Ranger enabled breakthrough science that had never before been possible, and provided groundbreaking opportunities in computational science & technology research, from parallel algorithms to fault tolerance, from scalable visualization to next generation programming languages.
